• How does Ruby's Enumerator object iterate externally over an internal iterator?

  - by Salman Paracha

  As per Ruby's documentation, the Enumerator object uses the each method (to enumerate) if no target method is provided to the to_enum or enum_for methods. Now, let's take the following monkey patch and its enumerator, as an example o = Object.new def o.each yield 1 yield 2 yield 3 end e = o.to_enum loop do puts e.next end Given that the Enumerator object uses the each method to answer when next is called, how do calls to the each method look like, every time next is called? Does the Enumeartor class pre-load all the contents of o.each and creates a local copy for enumeration? Or is there some sort of Ruby magic that hangs the operations at each yield statement until next is called on the enumeartor? If an internal copy is made, is it a deep copy? What about I/O objects that could be used for external enumeration? I'm using Ruby 1.9.2.

• Mysqli prepared insert statements always returning false

  - by user1754679

  I'm writing prepared statements that are supposed to insert data into a table, on a database that's been pre-selected in the variable $GLOBALS['mysqli']. The connection has been tested, and that's not the problem I'm having. I'm only running into trouble whenever my prepared statement involves INSERT INTO. I know the tablename, and field names are correct, but $stmt is ALWAYS false. What gives? $stmt = $GLOBALS['mysqli']->prepare("INSERT INTO audit_RefreshCount (user, count, lastrefresh) values (?,?,?)"); if ($stmt == TRUE) { $stmt->bindParam('ssi', $_SESSION['username'], '0', time()); //$stmt->bind_Param('ssi', $_SESSION['username'], '0', time()); // Also doesn't work. $stmt->execute(); }

• C - Discard the edges of an arbitrary level of a multidimensional array

  - by Medivh

  I have some geographical data, that I'm trying to parse into a usable format. The data is kept in NetCDF files, and is read out as a multidimensional array. My problem comes because the source of the geographical data has a strip of longitude on each side of the grid that overlaps the other side. That is, I have a longitude point of -1 degree, and another of 361 degrees. Unfortunately, I've got time, latitude, and sometimes height as dimensions in this array as well, and I have no way of predicting in advance where each dimension will be in the list (or if it's a three dimensional array, or a four dimensional array). Further complicating the problem, the array can be of floats, doubles or integers, so I have to pass it around as a void. Are there any NetCDF tools that I can use to pre-prepare the files? If not, how would you suggest I go about stripping the excess longitudes?

• What data structure would be the least painful DataTable replacement?

  - by MatthewMartin

  I'm storing a lot of sorted ~10 row 2 column/key value pairs in ASP.NET cache-- they're the data for dropdownlists. Right now they are all DataTables, which isn't very space efficient (the rule of thumb is 10x increase in size when data is strored in a dataset). Old Code DataTable table = dataAccess.GetDataTable(); dropDownList.DataSource = table; Hoped for new Code Unknown data = dataAccess.GetSomethingMoreSpaceEfficient(); dropDownList.DataSource = data; What pre-existing datastructures are similar enough to DataTable that would minimize code breakage and reduce the serialized size when stored in ASP.NET cache?

• "Inline" function call: function is never hit

  - by Shimrod

  Hi everybody. I'm trying to make a tabbed menu for the asp.net website I'm working on. One of the pre-requisite is obviously to color the current tab differently, so the user can know on which tab is currently is. To do this, I made this method in my code-behind: Protected Function GetCssClass(ByVal ctrl As LinkButton) As String If ctrl.ID = currentLink Then Return "current" Else Return String.Empty End If End Function and I call the method like this in my aspx page: <asp:LinkButton ID="LinkButton1" runat="server" PostBackUrl="/Default.aspx" CssClass="<%#GetCssClass(LinkButton1) %>" >Home</asp:LinkButton> <asp:LinkButton ID="LinkButton2" runat="server" PostBackUrl="/Directory/page1.aspx" CssClass="<%#GetCssClass(LinkButton2) %>" >Page1</asp:LinkButton> But the method is never hit... As I understand, the method should be called each time the LinkButton is drawn... Does someone have an idea why? Thanks in advance !

• Change the value of an existing onclick function

  - by Mark Peach

  I have a page that is pulling in via an iframe a page of html content from a pre-existing content management system, whose content I can not directly change. I want to use jquery to alter some of the links and button locations dynamically. For links within the page I was able to change the href attr values of <a href="/content.asp">more</a> from content.asp to content2.asp using $("a[href^='/content.asp']") .each(function() { this.href = this.href.replace("content.asp", "content2.asp"); }); But the page pulled in also has form buttons that contains javascript onclick functions e.g. <INPUT type="button" value="Add to basket" onClick="document.location='/shopping-basket.asp?mode=add&id_Product=1076';"> I basically want to use jquery to select any such buttons and change the shopping-basket.asp to shopping-basket2.asp How can I select these buttons/onclick functions and change the location string?

• How taxing would a game map grid be to a web browser?

  - by Vilx-

  Suppose we're making a strategy game (think Civilization) in a web browser. The game has a visible map portion - say 30x30 squares. Each square is 30x30px and has several overlaid images - the terrain, resources, units, roads, etc. The classical way of drawing this would be with a huge <table> where each cell would contain absolutely positioned images. It would probably be rendered in Javascript to reduce traffic. But it's still several thousand images and a huge table. Can the browser take it? Will the performance not drop below any acceptable limits? Alternatively I could keep a pre-rendered map image with as many overlays as possible, but that would be more work, I think.

• MySQL - How do I insert an additional where clause into this full-text search query

  - by Steven

  I want to add a WHERE clause to a full text search query (to limit to past 24 hours), but wherever I insert it I get Low Level Error. Is it possible to add the clause and if so, how? $query = "SELECT * WHERE story_time > time()-86400 AND MATCH (story_title) AGAINST ('".validate_input($_GET['q'])."' IN BOOLEAN MODE) AS Relevance FROM ".$config['db']['pre']."stories WHERE MATCH (story_title) AGAINST ('+".validate_input($_GET['q'])."' IN BOOLEAN MODE) HAVING Relevance > 0.2 ORDER BY Relevance DESC, story_time DESC LIMIT ".validate_input(($_GET['page']-1)*10).",10";

• Using Public/Private keys in reverse

  - by Wizzarding

  Hi, I have a situation where I need to make some data available for reading by anyone from a specific device, where the data is pre-loaded on the device, but I cannot allow anyone to create their own device and populate it with their own data in the same format. I know this sounds a little crazy, but there is a good reason! I was planning to use Public Key cryptography, encrypting the data with a public key, but then publishing the private key to anyone who wants to read the data. However, after looking at the RSACryptoServiceProvider and how it works it looks like I cannot just publish the private key as the private key can be used to create the public key. Could someone confirm that suspicion, or give me some hints on how I might be able to make this work! Many Thanks.

• Android: Custom Clock widget Service work-around?

  - by Anthony Forloney

  I was interested in developing a clock widget for the homescreen and upon reading Home Screen Widgets tutorial, is there a pre-existing Service I could reference for updating the current time rather than re-inventing the wheel? I have currently Retro Clock on my android phone and noticed that when I click it, it pops up the Alarm Clock settings, but with the default Google Analog Clock widget, upon click does nothing. Is that because the Retro Clock widget implements the Alarm Clock service? If so, how can I go about referencing that service? Or do I have this all wrong and misunderstood? Any help is appreciated. EDIT: I believe implementing the service to update the clock would drain the battery life tremendously, any ideas on a work around or help shed some light on any performance issues with using Service?

• Know if a Visual Studio Website project is recompiling itself in the background?

  - by jdk

  A number of team members update a central ASP.NET dev site (Website project, not a Web application type). Some kinds of changes cause a recompile/rebuild in it. The large website takes a while to recompile and we've noticed it will still seemingly serve out dynamic pages before everything is internally updated. During the site's "gestation" period, our mileage varies while hitting it. Sometimes we get a correct page, sometimes an compilation error page that will eventually be served up without a compilation error, and at other times an unexpected hybrid. Is it possible to query an ASP.NET website application to see if it's currently compiling or rebuilding itself? If so I would write a status page that the team could reference when they're getting weird behaviour, so they would know to wait. Update: Our team often edit files manually on the dev server. For production we'd make pre-compiled pushes. The dev environment is a little more malleable and ever-changing so I'm looking for a solution to reducing the "confusion" there.

• Setting Environment Variables For NMAKE Before Building A 'Makefile Solution'

  - by John Dibling

  I have an MSVC Makefile Project in which I need to set an environment variable before running NMAKE. For x64 builds I needs to set it to one value, and for x86 builds I need to set it to something else. So for example, when doing a build I would want to SET PLATFORM=win64 if I'm building a 64-bit compile, or SET PLATFORM=win32 if I'm building 32-bit. There does not appear to be an option to set environment variables or add a pre-build even for makefile projects. How do I do this? EDIT: Running MSVC 2008

• IPSec help on Windows 2003 please!!

  - by roacha

  Hey guys, I am trying to configure IPSec between a web and app server in our environment. I want all traffic between these two servers to use IPsec and be encrypted. These servers are on the same domain so i am currently using Kerebos for security, I have also tried pre-defined keys and nothing changed. When I try and ping between the servers I get "Negotiating IP Security" everytime. I have also confirmed that when I change "Require Security" to "Permit" everything works so IPSec is working, I believe its something with my security setup. Under the security tab both servers have the default 3DES keys first and then DES keys. I have also specified tunnel endpoints (the alternate server's IP). What am I missing? Thanks for any help..

• Add widgets to custom WordPress sidebars on theme activation?

  - by McGirl

  I'm working on a WordPress 3.0 multi-site installation. Each new blog will use the same theme with slight modifications (a custom Thesis install, if it matters). I'm trying to automate the set-up process for each new blog as much as possible. To that end, I'd like to automatically add widgets to my custom sidebars and widget-enabled footers. It'd be even better if the widgets could have pre-set parameters/content, that I or the blog owner could then go into the Widgets panel and edit. I've searched high and low and haven't been able to figure out a way to make this work. Any and all suggestions are welcome. Thanks so much!

• JavaScript using toString on a Function object to read text content

  - by mseeley

  Calling toString() on the function below returns different strings across browsers. I understand this is because ECMA-262 15.3.4.2 leaves wiggle room for each vendor. Chrome returns the comments in addition to all syntax. Sadly Firefox 3.6 omits the comments. Based on Firefox's behavior I haven't tested IE, Opera, or Safari. function foo() { /* comment */ var bar = true; } Specifically, I am attempting to embed meta data within a specially formatted comment block within a function. Later the return value of the functions toString() method would be parsed and values returned as an object. I've been unable to locate compatibility tables or alternatives to toString(). Does the community have any ideas? Btw, pre-processing JS files isn't an option. :( Thanks a lot. :)

• How to generate <a> tag from input fields

  - by NonProgrammer

  Using ASP.Net (in C#), I need to generate a tag that contains person's name, address, etc. I have barely any experience with ASP.NET (or .NET languages) and I am given this assignment. Could someone please guide me to correct path please? Link should look like this: https://example.com/PRR/Info/Login.aspx?SupplierId=36&RegisteredUserLogin=T000001&Mode=RegisteredLoginless&RegisteredModeFunction=AutoShowTotals&RegisteredModeFunction=AutoShowTotals&PayerCountry=FI&[email protected]&ExternalOrderId=1000123&ServiceId=286&Amount286=5000.00&PayerInfo286=T000001|10000123|type1|m&SuccessReturnURL=http://success.html&FailureReturnURL=http://failure.html&SuccessCallbackURL=http://youpay.com/p247/success.html&FailureCallbackURL=http://yourfailure.html following components/fields needs to be sent to API in order to pre-populate information for users: FirstName, LastName, SupplierID = integer, Person's userlogin (Should increment by 1. Example: person 1 = t00001. Person2 = t00002, etc.), PayerCountry, Email, amount For some reason, my management thinks that this is something a non-technical person can do! Any help would be appreciated! Thanks!

• Fastest Way to generate 1,000,000+ random numbers in python

  - by Sandro

  I am currently writing an app in python that needs to generate large amount of random numbers, FAST. Currently I have a scheme going that uses numpy to generate all of the numbers in a giant batch (about ~500,000 at a time). While this seems to be faster than python's implementation. I still need it to go faster. Any ideas? I'm open to writing it in C and embedding it in the program or doing w/e it takes. Constraints on the random numbers: A Set of numbers 7 numbers that can all have different bounds: eg: [0-X1, 0-X2, 0-X3, 0-X4, 0-X5, 0-X6, 0-X7] Currently I am generating a list of 7 numbers with random values from [0-1) then multiplying by [X1..X7] A Set of 13 numbers that all add up to 1 Currently just generating 13 numbers then dividing by their sum Any ideas? Would pre calculating these numbers and storing them in a file make this faster? Thanks!

• What do the external JSF libraries/frameworks add?

  - by kgrad

  I have seen mention of a bunch of external JSF Libraries such as ICEfaces, Richfaces, etc. However, I am unsure as to what these libraries actually add over just using JSF 2.0. Are they just additional components that are pre-built? I know that PrettyFaces adds URL rewriting, and I Believe that ICEFaces/Richfaces add Ajax enabled components? What are some other major component libraries, what are their benefits / why should people use them? Additionally, what does a framework like SEAM add over using straight JSF2 with EJB? Is MYFaces simply a different implementation of JSF?

• Why is simulink data type conversion block altering the data when it should be typecasting?

  - by Nick

  I am attempting to typecast some data from int32 to single. I first tried using the 'Data Type Conversion' block with single output data type and the Stored Integer option. However, I found that the datatype conversion block is not typecasting the data the way I expect it to. Am I using the block incorrectly, or is it failing to work as it should? temp1 (pre conversion): uint32: 1405695244 single: 1728356810752.000000 binary: 01010011110010010011010100001100 temp2 (post conversion): uint32: 1319604842 single: 1405695232.000000 binary: 01001110101001111001001001101010 By the way, I have gotten around the issue by using an embedded Matlab block to perform the typecasting operation.

• MSAccess Change Date Value Before Validation

  - by sisdog

  In a grid I have a date/time field where I would like the user to be able to type in short-hand formats for dates and times. For example, if they type in "435p" and then focus off of the cell they get the message "The value you entered isn't valid for this field.". Instead, I want to trap a pre-validationevent and change it to "4:35pm" for them. What event can I use? I've tried: LostFocus & BeforeUpdate: too late (validation fires before event) Dirty & OnChange: too early (they haven't left the cell yet) Or is there a way to turn off the native validation rule that is checking for date formats?
